In school problems in geometry, there is often a task to find the distance from a point to a straight line. Many schoolchildren, faced with such a task, fall into a stupor and do not know what to do, where to start solving the problem. It is important to remember that the distance from a point to a straight line is determined by the length of the perpendicular.

Instructions

Step 1

In order to find the distance from a point to, you need a perpendicular from that point to a given line.

Step 2

Look at the drawing that you drew according to the problem statement.

Step 3

If the required perpendicular from a point to a straight line is already present in the drawing (for example, the condition says that it is a perpendicular, height, an angle of 90 degrees is specified), find its length. You can be given the lengths of other sides, angles, shape properties. Use geometry theorems.

Step 4

If you see that the required perpendicular is present, but it is not known about it that it is a perpendicular, prove that it is exactly a perpendicular. Then find its length.

Step 5

If the required perpendicular is not yet available, build it. Be careful and careful when drawing, remember about the properties of the perpendicular. After constructing a perpendicular, think about how you can find its length. Find the length of the perpendicular.
